Cunderin station

Cunderdin was a single-platform crossing station on the Perth - Kalgoorlie route, with basic signalling facilities. The Electric Train Staff instruments were housed inside the station office, whilst the levers were beneath the awning in an enclosed area at the Kalgoorlie (left) end.

These photographs are undated, but were taken before the standard gauge line was built.

A nine-lever McKenzie & Holland frame controls the signals, whilst the points at either end of the station are worked by ground frames. The interlocking is achieved with Annett's Keys - the keys can be seen in their instruments at either end of the frame. When withdrawn, they lock the appropriate signals through the interlocking of the frame.

Although there are now no operational mechanical signal boxes in Western Australia, Annett's Keys are still used to lock points in remote locations. The keys for these are carried on the locomotives!

Adjuster wheels are provided behind some of the signal levers to cope with expansion and contraction of signal wires.

The diagram of the layout is shown below.
